Description
SMA Jack (Female) | Flat End | 4-Hole Flange Mount | Stainless Steel Body | Epoxy Captivation
The ROSNOL SMA2GFD50-1077B-EC/9X is a high-performance SMA jack (female) connector engineered for reliable RF signal integrity across DC to 18 GHz. This flange-mount design features a 4-hole layout with 6.35 mm (0.250 inch) hole spacing and utilizes a screw-lock coupling mechanism for secure engagement. The connector provides 50 Ω impedance, VSWR ≤ 1.30, and insertion loss ≤ 0.04 × √F(GHz), supporting stable operation in demanding RF environments. Mechanical characteristics include soldered center contact, epoxy captivation for enhanced durability, and recommended coupling torque between 0.8 Nm and 1.1 Nm. The robust build ensures consistent electrical and mechanical performance required in professional RF systems.Each component of the SMA2GFD50-1077B-EC/9X is constructed from high-grade materials to ensure long-term reliability. The center contact is made from beryllium copper with gold plating over a non-magnetic nickel-phosphorus underlayer, providing excellent conductivity and corrosion resistance. The outer body is stainless steel with passivation, ensuring structural strength and durability. The insulator is precision-molded PTFE for stable dielectric performance, and the connector incorporates epoxy captivation for secure mechanical retention. This SMA connector is suitable for RF, microwave, telecommunications, instrumentation, and defense-related applications requiring dependable flange-mount interconnections.
ROSNOL RF components are engineered to provide high-quality performance at competitive pricing, serving as a cost-effective alternative to major European and American brands. All products are manufactured in ISO 9001-certified facilities and fully comply with RoHS and REACH requirements, ensuring adherence to global environmental and safety standards.
